Specification of Letters Patent.A

To all whom t may concern.'

Be it known that I, RUSSELL W. LEWIS, a citizen of the United States, residing at Waukegan, in the county of Lake and State of Illinois, have invented a certain new and useful Improvement in Assembling and Banding Machines, of which the following is a specification, accompanied by drawings forming a part of the same.

My invention relates to packaging and banding machines, and in its preferred embodiment is of particular utility in connection with machines that are employed for packaging and banding envelops.

My invention in one of its aspects includes a series of receptacles which are to receive predetermined numbers of envelopsor other product units, there being mechanism that successively presents these receptacles to the mechanism that is employed to discharge the envelops, the first aforesaid mechanism being governed in its operationby the envelops themselves so that the envelop receptacles are not caused to travel until the receptacle which is being filled, has received its full quota of envelops. These receptacles are desirably formed in part by conveyer lates to mechanism for forming retaining bands about the groups of envelops or other product units and consists in mechanism for placing strips of paper or other suitableband making material about the groups of envelops and causing the union of the ends of these strips.

In the packaging of envelops the groups thereof are preferably compressed in conformity with the space they are ultimately to fill and while in such compressed state the bands are folded about the same.

My invention has other characteristics'and the various features thereof will be more fully explained by reference to the accompanying vdrawings showing thel preferred embodiment thereof and in which Figures 1 to 4, taken collectively, illustrate the machine, constructed in accordance with one embodiment of the invention, in side elevation; Figs. 5 to 8, taken collectively, illus- .trate the machine in end elevation; Fig. 9 1s a plan view illustrating the conveying and gumming mechanism; Figs. 1() and 11, taken collectively, illustrate a side View, partially 1n sectlon, of certain parts of the mechanism on lines 10-10, of Figs. 5, 6 and 8. Fig. 12 1s a view on a larger scale of certain of the mechanism illustrated at the right hand end of Flg. 10; Fig. 13 is a sectional view on line 1-13, Fig. 1, showing part of the mechamsm; Fig. 14 is a sectional view on line i 11; Fig. 15 is a sectional view on line 15-15, of Fig. 10; Fig. 16 is a detail View, in sectional elevation, illustrating a part of the banding mechamsm; Flg. 17 is a view of the mechanism shown in Fig. 16 with the parts in another adjustment; and Fig. 18 is a view of the mechanism shown in Figs. 16 and 17 in another adjustment.

Like parts are indicated by similar characters of reference throughout the different figures.

The invention is embodied in an envelop packaging and banding machine and the specific description of such embodiment will refer to such a machine, though it is to be understood that I do not limit myself to the nature of the product units which are grouped and banded. The machine of my invention is desirably coupled with an envelop making machine and has a fixed ratio of operation with respect to the operation of the envelop making machine, the driving mechanism for the two machines being preferably common. The envelops 1, Fig. 10, are discharged from a chain drier that carries these envelops from the envelop making machine, a chute 2 receiving the envelops and along which chute the envelops are fed singly by means of blades 3 carried by and projecting outwardly from an endless feeding belt or chain 4 and upon which blades the envelops rest in their travel in order that they may be dried. The blades 3 are desirably of skeleton formation as illustrated in Fig. 15 and the bottom,margins of these Ablades are inset so that the lower portions of 1 past the feeler 5 and the envelops in passing this feeler move the same 1n a counter clockwise direction so as to turn the shaft 6 in this direction, gravityserving to restore operated upon a number of times equal lto the x number of envelops to be contained in each package, such delay mechanism effects the coupling of a power devlce W1th the envelop receptacle conveyer for the purpose of removing one group ofenvelopsfrom alinement with the chute 2 and presenting a receiving space for another group of envelops in alinement with this chute. The delay mechanism, which is operated by the shaft 6, includes a link 7 joined at one end to an arm 8 fixed upon the shaft 6 and at its other end to an arm 9, attached to a short rocking shaft 1o, Fig. 12. A hooked latch 11 (Fig. 14) attached to the rocking shaft 10 engages a pin 12 carried upon the free end when the shaft 6 and envelop feeler 5 are in idle position. The movement of the feeler 5 by the passage of an envelop, rocks the shafts 6 and 10 and moves the latch -11 away from the pin 12, thereby allowing the free end of the pawl 13 to be carried into engagement with a ratchet wheel 19 by means of a spring 14 connecting the opposite end of the pawl with the upper arm of a bell crank lever 15, upon which the pawl 13 is pivotally mounted at 13.

The bell crank 15 carries at its lower end a cam roller 16 held in contact by a spring 16 with a cam 17 on a shaft 18 which is the main driving shaft ofthe machine to which power is applied. The bell crank 15 swings on a fixed stud 2O on which the ratchet Wheel 19 is loosely journaled. The upper arm of bell crank 15 carries a usher 151 arranged to enga-ge an arm 152 Journaled looselyon the stud 20. The u per end of the arm 15? carries a pushing p ate 153 having attached' to its upper edge a guard plate 154L that prevents an envelop from falling from the chute 2, until the pushing plate has been withdrawn to its right handposition. The arm 152 hasv a lug 155 carrying'an adjusting screw arranged to contact with the fixed framework and limit the swinging movement of the arm 152 toward -the right as actuated by a spring 15-, Fig. 12.

The number of teeth in the ratchet wheel y 19 equals the desired number of envelops to be contained in each group -or package, in the present instance, twenty-tive. At eachA swinging movement of the bell crank 15 the ratchet wheel 19 is moved one tooth, provided the actuating pawl 13 has been released from the hooked latch 11 by the passage of an envelop past the feler 5. When no envelop is delivered from the chute 2, the feeler 5,v hooked latch 11 and connecting parts are held by gravity to maintain the latch 11 in position-to engage the pin 12 and hold the pawl 13 out of engagement with the ratchet wheel 19. As the bell crank 1 5 is y swung in acounter clockwise direction by the spring 16', a pin 21 carried by the pawl 13 is brought into contact with a stationary cam 22 held by the framework of the machine, which rocks the pawl 13 to carry the pin 12 into engagement withthe hooked latch 11, causing the pawl 13 to be held in an 'inoperative position until released from the latch 11 by the passage-of an envelop past the feeler The ratchet wheel 19 is provided on one side with a iange 24, Fig. 14, having a notch 23 which, when the ratchet wheel has made a complete revolution upon the passage of twenty-tive envelops past the feeler 5, is brought vertically beneath the axis of the 1s presented to the upper Aend of a pivoted roc er arm 25 which is moved into the notch by the tension of a spring 26 applied to the lower end of the rocker arm. The lower end of the rocker arm carries a in 27 which contacts with a swinging latc 28 pivoted concentrically with the rocker arm 25 and norratchet wheel. In this position the notch 23 of an actuating pawl 13 and holds the free.

end of the pawl 13 in an elevated position mally enga 'ng a clutch actuating bell crank lever 29. he rocking movement of the arm 25 upon the grouping of each twenty-five envelops swings the latch 28 and disengages it from the clutch actuatin lever 29, whlch is then moved by the tension of a spring 30 to slide a clutch 31, having a spline connection with a shaft 32, into engagement with a constantly rotating clutch member 33 having an attached sprocket wheel 34, driven by a chain connection 35 from a sprocket wheel, not shown, having a fixed ratio of r0- tation to the main driving shaft 18.

The mechanism above described, comprising the feele'r 5, cam 17, ratchet wheel 19, i

and pusher plate 158 constitutes a counting mechanism which operates in conjunction with the clutching members'31 and 33, to bring the shaft 32 into operative connection with the driving mechanism whenever twenty-five envelops have been assembled.

the assembled envelops are compressed and a
